RE49836
This invention relates to sheet metal hangers which are used to connect a held or supported member to a holding or supporting member, which are often specifically a joist or truss member connected to a truss or girder member.
Structural engineers sometime prefer that hangers for trusses be connected to the vertical members of the truss, rather than the bottom chord which is in tension. There are various hangers which have a seat for supporting the held member, vertically disposed side members for providing lateral support to the held member and one or more back flanges disposed between the width defined by the first and second side members provided with a plurality of openings for attaching the hanger to the narrow vertical web of the supporting truss member.
The present invention provides a hanger that can have first and second side members having portions that are spaced relatively close together while having first and second back flanges disposed between portions of the first and second side flanges that are relatively wide and allow for optimal spacing of fasteners used to attach the hanger to the relatively narrow vertical web of the supporting truss.
This application teaches the construction of hanger for connecting a joist or supported truss member to a supporting truss or girder.
The application teaches a hanger for supporting a held member from a holding member that is provided with a seat member adapted for supporting the held member, first and second side members connected to the seat member, the first and second side members having lower portions and upper portions, the lower portions of the first and second side members each having inner an face and an outer face with the inner faces facing each other, and the upper portions of the first and second side members being connected to first and second back flanges respectively, the upper portions of the first and second side members each having an inner face and an outer face, and the first and second back flanges being adapted to be connected to the holding member by a plurality of fasteners, wherein the inner faces of the lower portions of the first and second side members and the inner faces of the upper portions of the first and second side members form reflex angles with each other.
By forming a reflex bend in the first and second side member between the inner side faces of the upper and lower portions of the first and second side members, the hanger can be formed with first and second side members having lower portions that are spaced relatively close together to provide support to a narrow supported member, while having inwardly bent back flange members that are connected to the upper portions of the first and second side members and that have lower portions that are disposed between the upper portions of the first and second side members and those lower portions of the first and second back flanges between the upper portions of the first and second side flanges span a width that is greater than the width between the lower portions of the first and second side members, allowing those lower portions of the back flange members to be relatively wide without having to overlap each other, and which also makes it easier to adequately space multiple fasteners in the lower portions of the back flange members.
In the preferred form the hanger is formed with a continuous single seat. In the preferred form, the hanger is made from a single blank of sheet metal and is formed by bending the blank into its three dimensional form. In the preferred form, the hanger is made from galvanized sheet steel and requires no welding in its fabrication or painting for protection.

In the preferred embodiment, the portions of the first and second back flanges 13 and 14 that are disposed between the upper portions 11 and 12 of the first and second side flanges 7 and 8 and do not extend above the side flanges 7 and 8 are considered the lower portions 41 and 42 of the first and second back flanges 13 and 14.
In the preferred embodiment, the lower portions 41 and 42 of the first and second back flanges 13 and 14 between the upper portions 11 and 12 of the first and second side members 7 and 8 span a width 53 that is greater than the width 54 between the lower portions 9 and 10 of the first and second side members 7 and 8.
In the preferred embodiment, the upper portions 11 and 12 of the first and second side members 7 and 8 span a maximum selected width 53, and the lower portions 9 and 10 of the first and second side members 7 and 8 span a second width 54 and the maximum selected width 53 between the upper portions 11 and 12 of the first and second side members 7 and 8 is greater than the width 54 between the lower portions 9 and 10 of the first and second side members 7 and 8.
In the preferred embodiment, the lower portions 41 and 42 of the back flanges 13 and 14 do not overlap each other, and the lower portions 41 and 42 are adapted to have multiple fasteners 15 driven through each of them into the supporting member 3. In the preferred embodiment, the second back member 14 is parallel and substantially aligned with the first back member 13.
In the preferred embodiment, the lower portions 41 and 42 of the first and second back flanges 13 and 14 are only attached to the first and second side members 7 and 8 at the upper portions 11 and 12 of the first and second side members 7 and 8 above the transverse bend lines 39 and 40. In the preferred embodiment, the lower portions 41 and 42 of the first and second back flanges 13 and 14 are connected to the upper portions 11 and 12 of the first and second side members 7 and 8 close to the transverse bends 39 and 40 in the first and second side members 7 and 8.
Preferably, the hanger 1 of the present invention is constructed from a single blank member of galvanized sheet steel (7 Gauge G90) without requiring any welding or painting. In the preferred embodiment, the hanger 1 is formed by bending along substantially straight bend lines and all bends have a radius of one thickness of the metal.
In the preferred embodiment, the hanger 1 is designed for attachment to a vertically elongated member 55 that is part of the larger supporting member 3 such as a webbed truss. In the preferred embodiment, the vertically disposed, elongated member is a web member 55 of the truss. In the preferred embodiment, the vertically disposed, elongated member 55 of the supporting truss has a selected maximum width 56 for the receipt of fasteners 15 for attaching the hanger 1 to the supporting member.
In the preferred embodiment, the first and second back flanges 13 and 14 are disposed a selected distance above the seat member 4 of the hanger 1. When the supporting member 3 is a truss formed with a bottom chord 57, a top chord and web members 55 connecting the top and bottom chords, it is desirable to not connect the hanger 1 to the bottom chord 57 of the truss 3. In the preferred embodiment of the hanger 1 which is designed for attaching to a truss 3 having a bottom chord 57 from wood having a nominal height of 6″, the first and second back flanges 13 and 14 are preferably formed a selected distance above the seat member 4 and the lowest of the openings 48 in the first and second back members 13 and 14 for receiving a fastener 15 is disposed above 6″ from the seat member 4. In the preferred embodiment the supporting member 3 and the supported member 2 are multi-ply girder trusses made from Southern Pine or an equivalent, and the fasteners used are Simpson Strong-Drive SDS ¼×3 fasteners. The minimum width of the vertical web member of the 55 of the supporting member 3 is nominally 6 inches in width as in a standard 2×6 piece of US lumber.
The hanger 1 of the preferred embodiment is formed on an progressive die with minimal waste of the sheet metal from which the blanks are made by taking a sheet metal blank, bending the first and second side members 7 and 8 downwardly from the seat member 4, bending the upper portions 11 and 12 of the first and second side members 7 and 8 upwardly from the lower portions 9 and 10 of the first and second side members 7 and 8, and then bending the first and second back members 13 and 14 downwardly from the upper portions 11 and 12 of the first and second side members 7 and 8. Openings 45 and 48 are provided in the hanger 1 for receiving fasteners 15 and 16 at designated points.
